Pen v Sword: Syrian cartoonist Ali Ferzat on challenging the Assad regime

Provocative artworks by a Syrian political cartoonist have gone on display in London.

Without Words, an exhibition organised by the Mosaic charity, features the work of Ali Ferzat.

He is living in exile, after being tortured by the Syrian regime, but continues to challenge it through his work.
